Virtual Reality may be a way to get over your fear. Get a vr headset like https://www.oculus.com/ or https://www.htcvive.com/us/ and a computer powerfull enough to run it well, a steering wheel and a program like http://americantrucksimulator.com/
You can demo the units at Microsoft stores, Microcenter, and some Best Buys.
I agree Idaho is definitely coming out in 2020 and is very likely the next DLC, Idaho and all the other states that border the base game have been outlined on the official website since the game came out.
They've just been adding the states in as they go along, it just so happens that now Idaho is the last state bordering the base game that hasn't been made yet, so it really stands out.
Excalibur are the publishers of SCS, but they only publish games to the U.K. not the rest of the world. CD Projekt Red publishes SCS games to Poland, and the same carries to different countries with different publishers.
What I mentioned above may be all lies so don't take my word for it.
The safest place to get the game right now is the official website.
